Light emitting device addressed spatial light modulator

Abstract

An optically addressed spatial light modulator may be formed with an integrated light emitting device display. The light emitting device display may be formed of a size and cost that optimizes the overall modulator design. In addition, by integrating the modulator and display devices, the overall size of the spatial light modulator may be reduced in some embodiments.

1. A spatial light modulator comprising:
 a light valve; and  
 an integrated organic light emitting device display including an integrated circuit substrate, said display covered by said light valve.  
 
   
   
     2. The modulator of  claim 1  wherein said device display is arranged to develop a write beam for said light valve. 
   
   
     3. The modulator of  claim 1  wherein the region between said light valve and said display is sealed. 
   
   
     4. The modulator of  claim 2  wherein said write beam is different from a read beam. 
   
   
     5. The modulator of  claim 2  wherein said write beam is the same as a read beam. 
   
   
     6. The modulator of  claim 1  including a microlens array between said light valve and said display. 
   
   
     7. The modulator of  claim 1  including a filter between said light valve and said display.
